三位虛擬流行偶像在未來感十足的音樂廳全息舞台上，以同步舞步登台演出

提示詞

建立一個寬幅 16:9 的動漫偶像演唱會場景，位於未來感全息舞台上，畫面中恰好有三位年輕女性虛擬流行偶像排成一列，表演同步編舞：一隻手筆直向上舉起，食指指向天空。中央的偶像是主唱，位置稍微靠近鏡頭；她留著長長的粉彩粉紅色雙馬尾，擁有柔和的粉紅色眼睛，以及溫柔而自信的微笑。左側偶像留著短款金色鮑伯頭，臉上帶著溫暖的笑容。右側偶像留著帶有鮮明藍色挑染的短黑髮，一隻眼睛部分被瀏海遮住，神情冷酷。三人都穿著相同的深海軍藍星空全息迷你洋裝：帶有心形領口的亮面馬甲式上身、透膚的黑色長袖、荷葉邊短裙、閃耀的星座般星星圖案、胸前的小星星裝飾、黑色頸圈、腕套，以及帶有星星細節的深色大腿襪。舞台背景是一座宏偉的科幻演唱會大廳，擁有發光的藍色水晶拱門、圓形金屬結構、一排排微小燈光、橫掃而過的白色雷射光束、朦朧的青色全息影像，以及她們身後若隱若現的旋轉木馬馬匹剪影或宇宙投影。使用明亮的藍色與紫羅蘭色燈光、高能量 J-pop 現場演出的氛圍、光亮反射、電影感景深、柔和泛光、細緻的動漫渲染、精緻的 GPT-image 風格，不要有可見文字，不要有浮水印，除了三位偶像之外不要有其他表演者。

Create a wide 16:9 anime idol concert scene on a futuristic holographic stage, featuring exactly three young female virtual pop idols standing in a row and performing synchronized choreography with one arm raised straight upward and index finger pointing to the sky. The center idol is the lead, slightly closer to camera, with long pastel pink twin tails, soft pink eyes, and a gentle confident smile. The left idol has short blonde bob hair and a warm smile. The right idol has short black hair with vivid blue highlights, one eye partly hidden by bangs, and a cool expression. All three wear matching dark navy starry holographic mini dresses: glossy corset bodices with sweetheart necklines, sheer long black sleeves, ruffled short skirts, sparkling constellation-like star patterns, small star ornaments at the chest, black chokers, wrist cuffs, and thigh-high dark stockings with star details. The stage background is a grand sci-fi concert hall with glowing blue crystalline arches, circular metallic structures, rows of tiny lights, sweeping white laser beams, misty cyan holograms, and faint carousel-like horse silhouettes or cosmic projections behind them. Use luminous blue and violet lighting, high-energy J-pop live performance atmosphere, glossy reflections, cinematic depth of field, soft bloom, detailed anime rendering, polished GPT-image style, no visible text, no watermark, no extra performers beyond the three idols.
